VST Smart Under Cabinet Lighting
Score: 82/100
Cefrank Smart WiFi Puck Lights
Score: 83/100Rankings

Cefrank Smart WiFi Puck Lights deliver adjustable white light from 2700 K to 6000 K with high CRI and durable aviation-aluminum housing, controllable via Alexa, Google Assistant, or app. They lack RGB color options and the physical dimmer can be hard to access. Perfect for tech-savvy users needing bright, energy-efficient task lighting.

VST's smart under-cabinet bars combine UL-listed safety with high CRI and impressive luminous efficiency, offering versatile Alexa and Google control plus handwave activation. They are limited by lack of water resistance and a fixed bar length. Best for users who need bright, color-accurate lighting in dry indoor spaces with multiple smart control options.

Professional reviewers and editors commend the VST bars for their UL-listed safety, high CRI 93+ color accuracy, and seamless no-shadow lighting, emphasizing the convenience of Alexa and Google integration. However, they criticize the lack of water resistance, the fixed 12-inch bar length that may require extra kits for larger installations, and the absence of a battery-powered option.
Everyday users generally praise the easy adhesive setup, bright 1050-lumens output, and versatile smart controls such as voice and handwave activation. Common concerns revolve around the product's restriction to dry indoor spaces, the limited bar length for extensive runs, and the lack of a battery backup for flexible placement.
